FLY OR IN seer-1MP.

SPECIFIGATION forming part of Letters Patent No. 742,304, dated October27, 1903. Application filed January 26,1901. Renewed September 4, 1903.fiierial No. 171,925. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH ADDISON FRAN- 01s, irrigation engineer, asubject of the Queen of Great Britain and Ireland, and a resident of 20Charles street, Nor-"wood, in the State of South Australia, Australia,have invented a certain new and Improved Buzz-Fly or Insect Trap, ofwhich the following is a specification.

This invention is designed for the capture and destruction of flies andother insects.

It consists in a specially-designed trough or open or partly-open tubemade of metal, paper, or other suitable material and of such a sectionalform that when fixed in position, preferably againsta window-pane,insects or files can readily enter the trough, but owing ,to itsconstruction cannot easily escape therefrom. p

In the accompanying drawings, Figure 1 shows a portion of a window withmy trap in position. Fig. 2 shows aclip for holding the trap in place.Fig. 3 is a side view of the trap, showing the side which is in contactwith the window. Fig. 4 is a vertical crosssection on line a b of Fig.3. Figs. 5 and 6 are side View and vertical cross-section, respectively,of a modified construction of my trap.

My specially-designed trough is formed of a tube A, with a slot oropening B along the whole or part of its length, and one edge 0 of thetube when the appliance is in position impinges horizontally against atransparent vertical surface,such as,prefe rably,a windowpane H. Theplate A, forming the trough, curves downward from this edge 0,thenupward and over till the other edge D forms the other boundary ofthe longitudinal opening, parallel to but a slight distance from thepane. This upper edge D is preferably somewhat curved inward, formingabaffle which effectually prevents the flies or insects escaping. Theends of the tube portion are closed by suitable caps E, having aperpendicular edge to hold the tube in correct position against the paneH. When the opening B extends for only a portion of the length of thetube, as in Figs. 5 and 6, one of the'caps E is made to slide into theend, so as to be removable for cleaning. In this case the inward.

This attachbuttons. .1 have found the best method to be a clip such asthat shown in Fig. 2.

Although a curved shape such as above described is what I have so farfound best, the trough may be formed ofova'l, three-cornered, or othershape, provided the essential feature of the opening next the pane isembodied as and for the purpose set forth.

My trap is preferably used in conjunction with some destructive powderor sticky or enticing or other material, such as those in common use.Instead, however, of being spread about, the buzz powder or poisonpowder or other material is by this trough concentrated in onecontinuous streak all along the bottom of the trough, so that itsproperties operate effectively upon the flies or other insectsimmediately they enter and cause death or stupefaction. Consequently myappliance is very efiective with the use of only a very small quantityof powder or other material.

Another advantage of this appliance is that the flies are all collectedtogether and can be emptied out and the trough cleansed with greatfacility.

The trough may be used without any powder or material, in whichcase theslot-opening would be made smallerthan when such materials are used.

Having described my' invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a fly-trap, the combination of a tube presenting an edge adaptedtoimpinge against a window-pane,'a partially-covered trough and adownwardly-projected baffle spaced slightly away from said edge to forma slot between said edge and the pane, and said 7 baffle, caps adaptedto close the ends of said tube, said caps presenting an edge on the.

same vertical plane as said edge whereby the latter is held in theproper position relative to said pane, and means whereby said trap issustained in such position.

2. In a fly-trap, the combination of a tube presentingan edge adapted toimpinge against a Window pane, a partially -c0vered trough and adownwardly-projected baffle spaced slightly away from said edge to forma slot between said edge and the pane, and said baftle, and removablecaps adapted to close the ends of said tube, said caps presenting anedge on the same vertical plane as said edge whereby said edge is heldin the proper position relative to said pane, and means whereby saidtrap is sustained in such relation.

3. In a fly-trap, the combination of a tube presenting an edge adaptedto impinge against a windowpane, a partiallycovered trough and adownwardly-projected baffle spaced slightly away from said edge to forma slot between said edge and the pane, and said baffle, caps adapted toclose the ends of said tube, said caps presenting an edge on the samevertical plane as said edge whereby the latter is held in the properposition relative to said pane and a clip adapted to be secured to theframe and to sustain said tube in such position.

In testimony that I claim the foregoing as my invention I have signed myname, in the presence of two witnesses, this 29th day of November, 1900.
